Taxonomy and Systematics at Glasgow - About taxonomy and systematics at the University of Glasgow, with links to other internet resources on these subjects.
Tree of Life - A project containing information about the diversity of organisms on Earth, their history, and characteristics. The information is linked together in the form of the evolutionary tree that connects all organisms to each other.

Universal Biological Indexer and Organizer - A networked information service for biological information resources, based upon the Taxonomic Name Server, a thesaurus of taxonomic information.
PAUP*
- PAUP is the most widely used package for phylogenetic inference, and now implements maximum likelihood and distance methods as well as various forms of parsimony. Powerful and very easy to use, particularly the Mac version.
PHYLIP
- Joe Felsenstein's suite of programs implementing perhaps the widest range of phylogenetic inference package. The most widely distributed phylogeny software. Includes distance, likelihood and parsimony methods for a wide range of different types of data, and runs on most platforms.
Clann: Software for Supertree Methods - Clann implements a large number of supertree methods for reconstructing phylogenies from sets of input phylogenetic trees.
Component - For analysis of phylogenies. Includes a wide range of randomization methods, consensus methods, tree comparison measures, and calculates reconciled trees. Now aging, and available only for Windows machines, but still has some unique features. Much of the functionality is now replaced by RadCon, GeneTree, TreeMap and the latest release of PAUP.
GeneTree - Uses reconciled trees to compare gene trees and species trees, explaining incongruence between the phylogenies by postulating horizontal transfer, gene duplication and loss events. Reprints of papers describing the methods are available from the GeneTree web page. Available for Macintosh and Windows.
MacClade - A powerful Macintosh package for phylogenetic analysis. Not intended as a stand-alone tool to infer phylogeny, but excels in studying character evolution. Also provides tools for entering and editing data and phylogenies and producing attractive tree diagrams and charts.
Mesquite - Experimental, modular software for evolutionary biology, designed to help biologists analyze comparative data about organisms.
MrBayes - Open source software for estimation of phylogenies using Bayesian inference.
NONA - Freeware software for phylogenetic analyses using parsimony.
PAML - Phylogenetic analyses of DNA or protein sequences using maximum likelihood.
Phylodendron - Java application for drawing phylogenetic trees. Allows you to save in various formats, print, edit, modify, and adorn the tree, and should work on any java runtime platform.
Phylo-Win - Graphical color interface for molecular phylogenetic inference. It performs neighbor-joining, parsimony, and maximum likelihood methods and bootstrap with any of them.
r8s - Open source software for estimating absolute rates of molecular evolution and divergence times on phylogenetic trees.
Tree Puzzle - Computer program to reconstruct phylogenetic trees from molecular sequence data by maximum likelihood.
TreeMap - Experimental program for comparing host and parasite trees.
